Microwave Propagation Based on Multi-Service Application in Power Plant

Microwave communication system has the advantages of frequency bandwidth, large channel capacity, suitable for transmission signals of video and other broadband signals. Electromagnetic interference in power plant is extremely complicated and there are many hidden trouble. In this paper, a kind of comprehensive information communication system based on multicarrier technology in power plant is presented. This system makes wire communication combined mutually with wireless communication by tandem adapter. The network conversion unit was designed, and connected with microwave communications to form the communications network. The system can transmit monitor images, control signals, fixed telephone and many other services, makes use of the advantage of OFDM technology to provide many kinds of access service.. The system not only fulfils the usual demand of produce communication monitoring, but also considers sudden accident. System structure of the powered communication and hardware was designed. From the work condition, the system can meet the requirements of the measurement and control in accuracy, real-time capacity and has high reliability.
